PQWER BALHVG PRESS.

Application filed January it, 1925. Serial No. 1,565.

My invention hes reference to power baling presses, and is speciallydesigned for use in large stores and factories, where there is aconsiderable accumulation of waste paper and similar refuse matter, litis of that clam in which it is intended to have the materiel ted in atthe top, end one of the 2 features thereof consists in simple and novelmechanism for tipping the platen to one side, out of the way, at theupper end of its movement.

The device includes s. receptacle for the waste material, having hinge-dside plates, which, with angular end extensions, comprise three sides ofthe receptacle, and which, when open, permit the contents of the mo.-

chine to he approached and removed from either side, as desired.

The machine is shown and described herein as heing arranged for anddriven by electricnl means, but the 5 me can be readily adopted foroperation y other lrinds of power, The use of electric power insures aquick response to the requirements of the operating mechanism, andrenders the same more easily handled. This includes devices forautomatically arresting the movement oi the platen dowardly, in thecompressing operation, when the pressure attains a predeterminedintensity. Limit switches are also installed in connection with theelectrical system, to automatically checlr the movement of the platen ata point in its upward movement, and at another point in its downwardmovement. 17*

The above-named, and other features and advantages of the invention willmore fully ap cur from the following specification, re erence being hadto the accompanying drawings, in which:

Z is an end view of the superstructure, with port of the frame cut away.

formed of a pair of I-beams 1, united by cross-plates 2, provided. attheir edges with ribs 3, united at a central point by cross-ribs l2.Between the plates 2 is fined a floor 5. provided at regular intervalswith channels 8, for the passage of wires in binding the completed holeof paper. Near the ends of the base are supported corner-posts 7 and 8,united at front and back by channel-pistes 9. Each pair of said posts isalso united at their upper ends by cross-plates 10, and fun ther bracedby cross-ties ll. (Ti 5;)

The receptacle for the material is termed ot a pair of spaced-apartend-plates 12. to the outer edges of which are hinged side plates 13.bent at their free ends into endplates 14, parallel with the plates 12,and similarly spaced. The edges of the endplates it are reinforced byangle-plates 15. and the inner edges of the plates 12 are similarlystrengthened hy angle-plates 16. (Fig. 8.) The outer edges of the plates12 are bent at a right angle and connected by plates 1'8 with the posts.The doors 13 may be locked in a closed position by fastening means shownin Fig. 5 of the drawings, consisting of e pair of bolts 18 slidablymounted on the outer faces of the end-plates it, and adapted forengagement with openings in plates 19,-fixed to the frame of themachine. The bolts 18 are connected by links 20 with the inner ends of apair of levers 21. pivoted to the end-plates id, as at b. Atthe lowerends of the plates it are slidably mounted it pair of bolts 22, adaptedto enter openings in the lower part of the frame, not shown in thedrawings. The bolts 22 are united by links 23 with the levers 21, atpoints between the tulcrums and outer ends of said levers. A movement ofeither of said levers operates to simultaneously lock or release theholts connected therewith. The fastening means just described. when in aloclred position, provide as rigid resistance againstthe pres sureexerted in the receptacle, either in the direction of the side plates 13or end plates i l. I

Secured to the outer faces of the posts till lttd

3 are spacers 25, to which is secured plots I tain devices used incontrolling the operation of the machine, which will be hereinafter morefully set forth.

Fixed to the inner faces of the crossplates 10 is a pair of bearings 27,(Fig. 3) from which is supported a pair of shafts 28, so asto berotatable therein. Said shafts are provided with threads 29, and thelower end of each of said shafts is united in'a bearing in one of thetie-ribs 4. The lower end of each of said shafts is threaded to receivea nut 31, above which is fixed to the shaft a helical gear wheel 32,separated from the bearing 30 by plates 33, provided in their adjacentfaces with ball races for a series of balls 34.

On each of the shafts 28 is a traveller 35, internally threaded tocorrespond with the threads on said shafts, said travellers being fittedwith trunnions 36, upon which are rockingly mounted bearings 37, fromwhich shafts 38 are projected inwardly.

Rockingly supported on said shafts is' a cross-beam 39, by means ofbearings 40 on the ends of said cross-beam. Fixed to the lower face ofthe cross-beam 39 is a series of channel-plates 41, comprising thecompression member or platen of the machine, such platen being of asuitable, size to move vertically in the receptacle. 'A coincidentrotation of the shafts 28 operates to move the travellers 35 and partssupported thereby upwardly or downwardly, depending upon the directionof rotation of said shafts.

Movement is imparted to the shafts 28 from a shaft 43 rotatably mountedin the base of the machine, and upon which are fixed gear-pinions 44, inengagement with the wheels 32 on the lower ends of the shafts 28.Movement of the shaft 43 is derived from an electric motor 45, in oneend of the base, by means of a gear-pinion 46 on the motor shaft, inmesh with a gear-wheel 47 on the shaft 43. The pinion 46 is considerablysmaller than the wheel 47 so that the speed of such wheel and the shaft43 will be correspondingly reduced.

The upper ends of the shafts 28 are threaded, and titted with nuts 48,between which and the bearings 27 are inserted ballbearing plates 49 and50, (Fig. 4) separated by balls 51. In the greater part of its movementportions of the cross-beam 39 near the ends thereof travel in thechannels in the ends of the receptacle, and in continuations of suchchannels formed by ex tension-s 15 in the superstructure. When theplaten is supported at a point where it is not in engagement with thematerial in the receptacle the weight of such platen and appurtenantdevices will be sustained entirely by the bearings 27 and anti-frictiondevices thereon, but upon the platen being moved downwardly intoengagement with the material in the receptacle, and beginning to exert apressure thereon, the direction of the load is shifted, and a forceexerted by the platen and travellers 35 in an upward direction upon thescrews 29. The resistance of the mechanism at the upper ends of theshafts 28 is thereupon transferred to the lower ends thereof, the upwardstress being borne by the anti-friction devices provided at that point.Said shafts 28 are capable of a limited amount of vertical movement inthe bearings 27 and 30, to allow for the transfer from one set ofresistance devices to the other.

Connected with the outer ends of the bearings 40, so as to be rotatabletherewith. are gear-pinions 53, the teeth of which are adapted to engagethe teeth of a pair of This leaves the top of the vmachine clear for thedelivery of material into the receptacle. ellers the platen is rockedback into position again, ready for its downward move ment. Thesuperstructure is of a sufficient height to permit the platen to becarried to a considerable distance above the top of the receptacle, andthe return movement of such platen is in a combined inward and downwarddirection, making it possible to pile the material above the top of thereceptacle. the excess material being forced downwardly into thereceptacle in its downward movement. This gives a greater capacity tothe machine, than in those which can only be partially filled, or onlyfilled as far as the upper edge of the box.

The operation of the motor may be under the control of well-knownelectrical devices, stationed in encasements on the outer face of thepanel 26, as shown in Fig. 1. For example, the box 56 may contain asafety switch, under the control of a circuit breaking device in thecasing 57, so arranged that when the amperage of the current reaches apre-determined point, superinduced by the pressure exerted by the platenupon the contents of the receptacle, the circuit is automaticallybroken, and the machine ceases to operate. At 58 is shown an enclosurefor other electrical devices of a standard type, the purpose of which isto cause the motor to operate in a given direction, or the reverse Onthe return movement of the travthereof. These devices are underthecontrol of switches in a box 59, provided with a set of push-buttons 60,one of which operates to start the motor to move the platen in a adownward direction, one to cause an upward movement thereof, and anotherto interrupt the movement of the motor and platen.

' Limit switches are also provided, one at 62 ly as shown in Fig. 7. Itwill be evident that, as a matter, of convenience, the racks 54 can bearranged on either side of the machine, and the platen tippedaccordingly;

The trunnion support of the bearings gives a flexible connection to theends of the cross-beam 39 with the travellers 35, and prevents thethreads of such travellers becoming-jammed on the screws 29, in case agreater strain should come on one end of the platen and cross-beam thanon the other.

In Fig. 9 is shown a modified arrangement of the device, wherein aplaten is suspended by a cross-beam '66, supported at its ends on theshafts 38. replaced by segment-gears 67 which engage gear racks 68 inthe upper part of the frame.

The pinions 53 are By such engagement, and the continued upward movementof the shafts 38 the platen is swung to one'side, as shown in brokenlines in said Figure 9. The receptacle can then be filled through thetop as in the former case. a

What I claim, and desire to secure by Letters Patent, is: e

1. A baling press, comprising a receptacle,

open at the top, and capable of being opened at its sides; a pressmechanism vertically movable in said receptacle, and above the same,said mechanism being rockingly mounted at its ends; an impedimentsupported in the path of said press mechanism, near the upper end of themovement thereof; and means carried by said press mechanism capable of amobile engagement with said im ediment, causing a tipping movement 0said press mechanism to one side of the machine, during a continuedupward movement of said mechanism.

2.1. A baling press, comprising a receptacle having an open top; a pairof screws vertically supported at opposite ends of said receptacle;travellers on said screws; :1 press mechanism pivotally connected at itsends I with said travellers, and including a -platen device; gearpinions on the pivots of said pressmechanism; and gear racks supportedin the upper part of the machine, in the path fof said PIIIiOIlS, andadapted to rotate the same to rock the press mechanism and platen to oneside. of the machine.

In testimony whereof I afiix my signature.
